Application filed September 20, 1920 Serial No. 411,548.

T aZZ whom it may concern) Be it known that l, BnUNeoN S. h ioCn'rorr-EN, a citizen of the United States of America residing at Plainfield, inthe county of Union and State of New Jersey, have inventen certain newand useful Improvements in TV ringers, of which the following is aspecification.

This invention relates to clothes wringers and consists in certainimprovements in the construction thereof to be hereinafter fullydescribed and particularly pointed out in the claims.

The invention has for its object to provide means for instantiyreleasing the pressure on the rolls, when the operator get her handcaught by the rolls or for the purpose of releasing abnormally large orbunched articles which may be drawn between the rolls.

Other and further objects will be part apparent and in part described asthe specification is proceeded with.

In the accompanying drawings:

Figure 1 is a plan view or my invention;

Figure 2 is a vertical longitudinal sectional view of the same;

Figure 3 is a horizontal sectional view of the bushing;

Figure 4 is a side elevation of same;

Figure 5 is a plan view of sleeve showing a portion of the angle plate;

Figure 6 is a vertical sectional view at the same; and

Figure 7 is a diagrammatic view of s eeve and bushing showing manner inwhich they cooperate.

Referring more particularly to the drawings in which like referencenumerals refer to corresponding parts throughout the several views 5denotes a wringer frame comprising end bars or uprigl'its 6 and sidebars 7. Pressure rolls 8 only the upper one of: which is shown in thedrawing, are suitably mounted in the end bars 6 and are maintained undersuitable compression by means of spiral compression springs 10 seated attheir lower ends against the bearing blocks 11 of the roll 8, it beingunderstood that these bearing blocks are slidably mounted in the end bar6. Seated in the tops of the compression springs 10 are a pair of cupshaped members 9 in turn engaged by compression screws 12 the mountingand operation of which will be presently de scribed.

Bolted to and extending over the tops of the end bars 6 of the wringerframe are a pair 01' angle plates 13 having upstancing sleeves 1 iormedintegral therewith. The interior of the sleeves 1d are provided withvertical ribs r projections 15 having inclined faces 16 adapted toengage or mesh with the inclined faces 17 of vertical ribs orprojections 18 formed on bushings 19 turn rotatably mounted in thesleeves 1%. These ribs 15 and 18 in effect form spiral threads. Thebores 20 of the bushings 19 are threaded or the reception of thecompression screws 2. Consequently when the screws 12 are crowed down bymeans of the crank handles 21] rined thereon, the movable upper com- 1.-sion roll may be placed under any desired in; ession, through theaction of the com- .5 ion springs 10.

Owing to the fact that the normal upward thrust of the compression roll8 tends to rotate the bushings 19 in the sleeves 14: in an anticlockwisedirection thus ausing the bushings and with them the compression screwsto move upwardly thereby reducing the compression or the rolls, somemeans must be provided for locking the bushings against such rotationuntil manually released. This is accomplished by means of a rod or thelike 22 adapted to exteno diagonally across the top of the wringer withits ends seated in diagonally disposed pockets :23 formed in the angleplates 13. The ends of this rod when so seated lie directly in the pathof rotation of the arms formed on the bushings and of course serve tohold the bushings stationary.

ln the event of the operator having her hand drawn between the rolls,all that is necessary for her to do to relieve the compression betweenand permit separation of the rolls is to strike or bear against the rod22 causing the latter to be pushed out of the open ends 25 of thepockets 23, thus freeing the rod from engagement with the arms 24:. Therod can be readily pushed out of the pockets from either side of thewringer frame and the release oi one end of the rod automaticallyresults in the release of the 1 the ribs 15.

sleeves when the ribs 18 are aligned with the spaces between the ribs15. 7

Any suitable means such as chains 27 may be employed to prevent the rod22 from fall ing off or down into the interior of the frame.

Having thus described my invention, what I claim is:

l. A clothes wringer comprising a frame,

rolls and compression means therefor mounted in said frame, angle platessecured to said frame at each end thereof, said plates being formed withsleeves having interior ribsthereon, bushings rotatablv and slidablymounted. in said sleeves and having exterior ribs, the ribs on saidsleeves and said bushings having engaging oppositely inclined portions,compression screws mounted in said bushings engaging said compressionmeans whereby the upward thrust of said rolls causes said bushings torotate upwardly in said sleeves, and means for normally pre venting suchupward movement of said bushing. 2. A clothes wringer comprising aframe, rolls and compression means therefor mounted in said frame, abushing rotatably and slidably mounted in said frame,a compression screwcarried by said bushing engaging said compression means permitting theraising of saidbushing when rotated but pre venting such raising exceptwhen rotated, said bushing adapted to be raised in said frame by theupward thrust of the compression means to relieve said compression, andreadily releasable means for preventing such rotation of the bushing.

3. A clothes wringer comprising a frame, rolls and compression meanstherefor mounted in said frame, sleeves mounted on each end of theframe, bushings :in said sleeves having arms thereon, said bushings andsleeves having ribs with inclined engaging portions, and compressionscrews carried by said bushings and engaging said compression meanswhereby said bushings are adapted to be rotatably raised in said sleevesby the upward thrust of said compression means to relieve thecompression between the rolls, and quick releasable means'extendingbetween the arms on said bushings for normally preventing such rotationof said bushings. i

i. A clothes wringer comprising a frame, rolls and compression meanstherefor mounted in said frame, sleeves mounted on opposite ends of theframe, bushings rotatably mounted in said sleeves, said sleeves andbushings having longitudinal spaced intermeshing ribs "formed withengaging inclined faces, compression screws carried by said bushingsengaging said compression means, whereby the upward thrust of saidcompression. means causes the bushings to rotate and. the ribs of saidbushings to ride upwardly between the ribs of said sleeves to relievethe compression between said rolls, means on the ribs of said bushingsadapted to limit said upward movement and means for normally preventingthe rotation of said bushings.

5. A clothes wringer comprising a frame, rolls and compression meanstherefor mounted in said frame, sleeves mounted on opposite ends of theframe, bushings rotatably mounted in said sleeves, said sleeves andbushings having spaced intermeshing ribs formed with inclined engagingfaces, compression. screws carried by said bushings engaging saidcompression means, whereby the upward thrust of said compression meanscauses the bushings to rotate and the ribs of said bushings to rideupwardly between the ribs of said sleeves, and quick releasable meansfor lockingsaid bushings against rotation.

In testimony whereof I affix my signature.
